CARBURETOB.

Application 1ed December 30, 1925.,.Seria1No. 78,374.

This invention relates to carburetors and 1t has for its obJect to provide a simple and inexpensive device of this character which manifold of an internal combustion engine,

F iO. 2 is a perspective View of the carburetor,

Fig. 3 is a horizontal sectional view therethrough,

Fig. 4 is a longitudinal sectional'view, upon line 4-4 ofF ig. 3, and

Fig. 5 is a transverse sectional view therethrough upon line 5 5 of Fig. 3.

Like numerals designate corresponding parts throughout the several figures of the drawing. Y

In the drawing, 5 designates'the exhaust manifold and 6 the intake manifold of an internal combustion engine. The carburetor 7 is connected with the intake manifold by a pipe 8, and with a source of gasoline supply by a pipe 9, and with a source of heated air by a pipe l0, the pipe 10 connecting with a stove 11, which surrounds the exhaust pipe of the engine. The carburetor proper comprises a box-like casing12, having a cover 13, and abottom 14. This casing is divided internally by partitions 15 and 16, into chamber 17, 18 and 19. Pipe 8 leads from the chamber 17 and the chambers 17 and 19are in communication with each other through a port 20. The chambers 18 and 19 are in communication withA leachV other through a port 21. The gasoline supply pipe 9 (see Fig. 3) conducts gasoline to the chamber 18, the gasoline passing from said chamber through port 21 to the chamber 19 and from the chamber 19 to the chamber 17 through the port 20. The pipe 8 leads from the'chamber 17 at a point above the level of thegasoline therein. Heated air through pipe 10 enters the carburetor at 22 (see Fig. A plurality of spaced V- shaped partitions 24E, 25, 26, 27 and 28, have ports 29, 30, 31, 32 and 33 formed therein, upon alternately opposite sides of the point of entry 22 of pipe 10, so'that the Vair is caused to travel through a tortuous passage- Way, as indicated by the arrows, finally passing through port 33 into chamber 19, thence through port'20 to chamber 17 and out through pipe 8 to the intake manifold 6. Thegasoline level in thev carburetor is such that a body of gasoline lies withinthe passages between the V-shaped partitions 24 to 28, this level being maintained at about the level of the ports; or in other words, the casing 12 is Amaintained about half full. It is common practice to maintain the gasoline at a predetermined level in structures of this character. Floats are usually resorted to for this purpose and I may accomplish the desired resultv in that way.

However, such float does not necessarily have to be located within the body 12 but might be located at anyy point in communication within the supply line 9. Thus, it will be seen that the pipe 8 leavesat a point above the level of the gasoline so that only vapor will be drawnl into said pipe. The air drawn in through pipe 1() bubbles up through the gasoline within partition 24 on its way to port 29. This bubbling of the gasoline agitates, to some degree, the gasoline in the adjacent passages. Thus, the air is thoroughly carbureted or impregnated with gasoline vapors, said vapors being iinally drawn off through pipe 8 to the intake manifold for use in the engine. While I have used the 'term gasoline in this specifi- A cation, it is to be understood that any other suitable volatile vliquid fuel is the equivalent thereof.

It is to be understood that the invention is not limited to the precise construction setV forth but that it includes Within its pur- 'view whatever changes fairly4 come Within either the terms or the spirit of theappended claim.

Having described my invention, what I claim is:

A carburetor comprising a casing, a pair of partitions therein Idividing said casing into three chambers, said partitions being provided with ports therethrough through which communication is established between said chambers, an air inlet pipe leading into the bottom of said casing, at the sidethereof remote from oneof said partitions, a plurality of spaced V shaped partitions between the point of entry of the air inlet pipe and the last named partition, each of said V- shaped partitions having a port formed therethrough, the ports in the successive partitions being dispose-cl on alternately opposite sides of the point of entry of said air inlet pipe, and an outlet pipe for oarburetecl air which lies at a point materially above the level of the ports through said V shaped 10 partitions.

In testimony whereof he ai'iixes his signature.`
